An Automatic 35mm A&B Composite Color Printer

Sidney P. Solow, Edward H. Reichard

A high-speed color printer for making A&B composite prints from 35mm original color negatives has been designed and constructed by Consolidated Film Industries. The printer, operating at 120 ft/min, incorporates fades and dissolves in the prints without the use of duplicate effects negatives. Scene-to-scene color and intensity changes, as well as variable length effects, are monitored by means of either a transistorized radio-frequency proximity cue detector or a notch contactor. The lamp-houses, readers and fader system are modifications of the latest Bell & Howell design, similar to those used in the B&H Additive Printers. A single light valve is employed for intensity control in this subtractive color printer; however, the lamp-houses are designed for future installation of two more light valves and dichroic mirrors, should conversion to additive color printing be desired. The printing machine is controlled by a punched paper tape which programs predetermined intensity changes and fade lengths.
